A review of the monitoring and management of Spotted-Wing Drosophila (Drosophila suzukii) in lowbush blueberrie

Abstract

The recent arrival of spotted-wing drosophilia (Drosophila suzukii) to eastern Canada is a major threat to the million dollar lowbush blueberry industry. The highly fecund female fly lays her eggs in ripe soft-skinned fruit. The maturing larvae consume the fruit interior, ultimately resulting in fruit collapse and decreased yield. Effective monitoring and management of this pest is essential for reducing the risk of export market closure and economic losses. In this literature review, an integrated pest management plan is developed that outlines current monitoring and management practices for the pest and considers preventative physical, chemical and biological controls.
